Check Digit Verification of cas no

The CAS Registry Mumber 55523-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,2 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55523-50:
(7*5)+(6*5)+(5*5)+(4*2)+(3*3)+(2*5)+(1*0)=117
117 % 10 = 7
So 55523-50-7 is a valid CAS Registry Number.

Highly stereoselective oxazaborolidinium ion catalyzed synthesis of (Z)-silyl enol ethers from alkyl aryl ketones and trimethylsilyldiazomethane

Kang, Byung Chul,Shim, Su Yong,Ryu, Do Hyun

supporting information, p. 2077 - 2079 (2014/05/06)

Highly stereoselective (Z)-silyl enol ethers were prepared from alkyl aryl ketones and trimethylsilyldiazomethane (TMSD) using an oxazaborolidinium ion catalyst. In addition, ring-expanded silyl enol ethers were successfully constructed from cyclic ketones. Their synthetic utilities were shown by sequential Mukaiyama aldol and [2 + 2]-cycloaddition reactions.
